Rebuild psycopg (and mxDateTime) but build them against python 2.1,
not 2.2.  You may need to modify the setup.py script to point it to
the right 'python' interpreter.  (the fact that the modules were
installed in the "wrong" place indicates that something is "wrong"
with your setup -- the modules were build and installed just fine for
python 2.2)  You'll definitely need the (C) headers from python 2.1 to
compile.  I don't know if zope's tarball comes with them or not.

I really can't help other than pointing out that problem because I
have pre-made packages for my distro that work quite well.



If Microsoft would build a car...

would have to pull over to the side of the road, close all of the car
windows, shut it off, restart it, and reopen the windows before you
could continue. For some reason you would simply accept this.
